    at what speeds?
    If I understand you correctly, the T-Mobile version works on AT&T's HSPA+ network? How about LTE?

    Yes that's right,should have been more specific.Download speeds are about 5.5 to 9 kbps, upload about 1.5 to 2.5 kbps.Funny I show only a 3G icon in notification bar instead of a 4g icon. I don't have LTE service yet.

    True 4g kicks in at 5.5mb and true lte @ 15.25mb but @10.25mb in USA is considered lte.....it may not be up that high long enough during speed test to register the icon

    Unless you have a T999-L version (Which has not been released as yet) you will not get LTE with any Carrier.
